Abstract

The paper contains description of conception, realization a tests of an accumulative heat exchanger. The appliance has a sectional construction with four cassettes filled with ceresine – a mixture of paraffins. The exchanger is dedicated for ventilation and cooling applications, especially in passive buildings. Usage of phase change materials is one of the most important topics in the whole area of energy storage. Series of tests have been done, during which both, the casing and the cover have been insulated, thereby thermal losses have been limited. Furthermore, paper presents an influence of insulation on the heat storage possibility in the proposed accumulative heat exchanger.
